Abstract: 990,792. Bearings. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 9, 1961 [Aug. 9, 1960], No. 28763/61. Heading F2A. A bearing incorporating a safety device in the event of seizure comprises a shaft supported in a bush 2 which is mounted in a housing 3 by a ball-bearing assembly. To prevent rotation between the bush and housing as the shaft rotates, lugs 10 and 16 attached to the housing 3 are located in a recess 22 and ramp 23 respectively in the bush. The lug 10 is attached to a spring-loaded piston 12 in a chamber 13. A spring-loaded finger 19 in the housing 3 bears against lug 16. When the shaft is rotating, lug 10 is withdrawn from the recess 22 in the bush by fluid pressure acting on the piston from between the bush and the shaft via openings 15 in the chamber 13. The annular groove 11 in the lug 10 is then in line with finger 19. Seizure between the bush and shaft effects displacement of the lug 16 by the ramp 23 in the bush due to rotation thereof, which then aligns opening 17 in lug 16 with the groove 11 and finger 19. The finger is then urged forward to hold both lugs in the withdrawn position. Further rotation of the bush and shaft in the ball-bearing causes severance of a wire 18 to terminate the power supply.

Abstract: 1,144,139. Reciprocating conveyers. DOWTY MECO Ltd. 22 June, 1967 [28 June, 1966], No. 28831/66. Heading B8A. [Also in Division F2] Arms mounted on the working face of an armoured flexible conveyer are moved angularly about fixed pivots through arcs so as to displace coal spillage away from a ramp plate 12 of the conveyer. In Fig. 1, arms 29 are pivoted on pins 30 and are reciprocable by a slide bar 27 actuated by a ram (23), Fig. 3 (not shown). The joints between pans of the conveyer permit some transverse and vertical flexibility. In place of the sector-shaped arms 29 the arms may be parallel-sided, Fig. 7 (not shown). The slide bars 27 of a plurality of ramp plates may be actuated by a single ram. In a further construction, Fig. 8 (not shown), a slide bar (40) is reciprocated by a chain sprocket (46) having a pin (48) which drives the bar. In Fig. 10 the drive between a rod 54 and a slide bar 51 is transmitted by a pair of split collet clamps 58 normally urged in opposite directions by a spring 65. When the rod 54 is reciprocated the wedging action of one of the collets causes the slide bar 51 to be reciprocated. Should the amplitude of oscillation of the rod 54 be excessive the collet clamp 58 engages a bearing 55 and driving engagement between the clamp and rod is released.

Abstract: 408,685. Winding yarns and threads. BRITISH CELANESE, Ltd., 22, Hanover Square, London, KINSELLA, E., and TAYLOR, W. I., c /o British Celanese, Spondon, near Derby. Oct. 15, 1932, No. 28840. [Class 120 (ii).] In winding cross-wound packages the package is supported between a driving-drum and a traverse-drum and the ratio of the speeds of the drums is varied during the formation of the package to prevent ribbon winding. Preferably the driving-drum is rotated at a constant speed, and the drums are arranged so that the greater part of the weight of the package is carried by the driving-drum, and so that, as the size of the package increases, its weight is disposed more nearly vertically upon the driving-drum, the nipping effect between the drums being thereby reduced relatively to the weight of the package and the reaction between the package and driving-drum maintained substantially constant. The invention is particularly applicable to the winding of artificial yarns continuously with their production as described in Specification 384,997. As shown, yarn packages 22, 23 are supported by driving-drums 20, 21 and grooved traverse-drums 18, 19. The driving- drums are driven by sprockets 36, 37 from the main sprocket 28, and the traverse-drums by sprockets 29, 31. The sprocket 29 is connected by means of a crank 43 with the main sprocket 28 and the crank is operated by worm gear 47 so that the speed of the sprocket 29 and of the driving-drums is varied. The packages are carried by links 26 and the shafts 38, 39 of the driving-drums are arranged slightly lower than the shafts 30, 32 of the traverse-drum so that the greater part of the weight of the carriage is taken by the driving-rollers. The Provisional Specification describes also an arrangement wherein the traverse-drum is driven from the package.
